I'm trying to make sense out of the question you posted and the only thing I can come up with that would explain the cryptic nature of your post is that you're some sort of secret agent, either for the Federal government, say, the NSA, Homeland Security, etc. or agent for the FSB, successor to the defunct Soviet Union's KGB or lastly perhaps employed by the NKSP, North Korean Secret Police, as undercover agent on a covert mission to infiltrate the Global Pedophilia Network (GPN) gain their confidence, have them reveal their organization, sources of illicit content distributed throughout their secret membership and eventually move your up the organization as Director.
Your status as uncover agent is, unlike that of England's top agent status which is classified as 007, license to kill, your special privileged agent status is classified as BB one and three quarters, license to chill.
I see your cryptic statement as means to making contact with your local support team who would instantly recognize your query about the North Pole launch as password that coneys to them your identity as agent for NKSP and to provide you full tactical, technical support for your reconnaissance mission in the infitration of the GPN. Good Luck.
Instead of all the gibberish, answer your own question: “.....what would they find if they lifted off from the South Pole, the very bottom of the Earth, and truly went “down”? That was going to be my second question but I got tired and went to bed. I figured I could wait until morning to find out.
